Paraclinoid aneurysms: is there a new endovascular standard?

AbstractObjectives: Paraclinoid aneurysms are challenging lesions to treat with traditional surgical and conventional endovascular techniques despite modern improvements in technique and technology. Flow diversion emerged recently as a promising new therapy that overcomes limitations related to the wide-neck and fusiform morphology, and importantly addresses the underlying diseased parent artery from which the aneurysm arises.Methods: We reviewed the current literature regarding the safety and efficacy of flow diversion therapy for treatment of paraclinoid aneurysms.Results: Early results suggest excellent ability for flow diversion to remodel the diseased parent artery and achieve durable complete angiographic occlusion of the aneurysm with acceptable rates of peri-procedural risk.Discussion: Flow diversion therapy can achieve durable and high rates of obliteration that surpass traditional methods of management for paraclinoid aneurysms. However, caution is warranted when considering this treatment modal...
